|A joint REWAS-LMD symposium on Recycling and Sustainability will be organized as a joint session with Cast Shop Technology. The usage of light metals in the aerospace, automotive and packaging industries has been rising due to their outstanding properties. The importance of recycling and sustainable metal casting has risen in the last decades dramatically due to the increasing demand on primary resources and environmental concerns. Innovative solutions are needed to increase the efficiency in metal processing and treatment for complex scraps. This joint session within the Cast Shop Technology explores novel and improved recycling technologies for complex scraps, mechanical and thermal pre-treatment of scraps, new recycling and refining processes, economic and environmental impacts of recycling, incl. life cycle assessment.
